BUENOS AIRES , Argentina -- Juan Roman Riquelme scored twice as Argentina beat Bolivia 3-0 to notch a third successive victory in the South American qualifiers for the 2010 World Cup on Saturday .

Juan Roman Riquelme celebrates after scoring his first goal in Argentina 's win against Bolivia .

The midfielder followed up his brace of spectacular free-kicks in the opening 2-0 victory against Chile to help put his country five points clear of second-placed Brazil , who play Peru in Lima on Sunday .

Riquelme again shrugged off his lack of club action with Villarreal , where he has fallen out with the Spanish side 's management , to net twice in the second spell after Sergio Aguero gave the home side a first-half lead .

The 19-year-old scored his first goal at international level five minutes before the interval after starting in a three-man attack with Carlos Tevez and Lionel Messi .

He headed home after Martin Demichelis nodded a cross from Manchester United striker Tevez back across goal .

Riquelme added the second 11 minutes after the break with a dipping free-kick which beat Carlos Arias from 25 yards , having been superbly denied by the keeper 's one-handed effort shortly beforehand .

And he finished off the scoring in the 73rd minute with a cool sidefoot finish after being set up by Messi to cap off a match in which captain Javier Zanetti made a record-breaking 116th appearance for Argentina .

Argentina next travel to Colombia on Tuesday , when winless Bolivia have an away clash with Venezuela .

In other South American qualifiers , Colombia beat Venezuela 1-0 , and Paraguay routed Ecuador 5-1 .
